Poll: Billboard.com's 2011 Mid-Year Music Awards

With calendars rolling over to July on Friday, 2011 is officially half-over -- and its first six months have offered some incredible moments for popular music. So far, 2011 has been the year in which Adele took her talents to the next level; Arcade Fire owned the big festivals; Jennifer Lopez made her long-awaited return to the spotlight; Wiz Khalifa became a household name; Chris Brown didn't have a good morning on "Good Morning America"; and Lady Gaga and Britney Spears sat comfortable at the top of our charts.
